"Now and again it is necessary to seclude yourself among deep mountains and hidden valleys to restore your link to the source of life. Breathe in and let yourself soar to the ends of the universe; breathe out and bring the cosmos back inside. Next, breathe up all the fecundity and vibrancy of the earth itself. Finally, blend the breath of heaven and the breath of earth with that of your own, becoming the Breath of Life itself" (Morihei Ueshiba, "The Art of Peace", trans. John Stevens)
